TRAP FOR AIVIALGAll/l.

SPEGIFIGATION forming part of Letters Patent No. 708,599, dated September 9, 190.2.

Application filed August '7, 1901. Serial No- 71,15'7. (No model.)

To all whom it may concern:

Be it known that I, GEORGE R. TUTTLE, a citizen of the United States, residing at Grass Valley, county of Nevada, State of California,

have invented certain new and useful Improvements in Traps for Amalgam; and I do hereby declare the following to be a full, clear, and exactdescription of the same.

The present invention is designed mainlycoming the loss of such amalgam as is'not col-- lected by the amalgamating-plates proper.

To comprehend the invention, reference should be had to the accompanying sheet of drawings, wherein Figure 1 is a broken View of an ordinary battery with the improved trap arranged therein. Fig. 2 is a plan view of a plate provided with a series of traps or cells for the amalgam. Fig. 3 is a detail view of one of the cells which constitute the trap, and Fig. 4 is a cross-sectional view on line a; 00, Fig. 2. v

In the drawings the letter A is used to indicate the battery or mortar of an ordinary stamp-mill, within which the ore is treated or worked and within which in the present case the trap is arranged.

The trap consists of a series of hollow metallic shells or cells A, preferably composed of tubing and circular in form. However,

the shape of the cells is an immaterial fea-.

ture of the invention. The interior of each cell is divided into' two compartments by means of the partition or liningpiece B, which partition or lining-piece is composed of copper. Each cell is composed of two dissimilar pieces of metal so associated as to constitute a voltaic battery, which attracts and deposits the amalgam upon the inner surface thereof. If desired, the cell-tube maybe composed-0f copper and the partition-piece of a dissimilar metal. Ordinarily the cells are arranged in series fitted within sockets a of a board or plate 13 When so arranged, the trap thus formed is secured to the chuckblock or cheek-plates of the battery. Still the location of the trap is immaterial, as it may be outside of the battery or one located therefrom.

within the outer edge of the die-ring O of the battery, as shown in Fig. 1 of the drawings. During the working of the stamps the ore is pulverized and the quicksilver thoroughly intermixed therewith. The freed gold is collected by the quicksilver within the battery, which amalgam being splashed and distributed during the action of the stamps works over the trap-cells and is caught and retained thereby.

Having thus described the invention, what is claimed as new, and desired to be protected by Letters Patent, is-

1. An amalgam-trap comprisinga plate having a recess therein, and a cell in said recess comprising a tubular body portion and a partition therein, said body portion and partition being composed of dissimilar metals, substantially as described.

2. An amalgam-trap comprising a plate having a recess therein, and a cell in said recess comprising a tubular body portion and a partition therein adapted to be inserted into or withdrawn from either end of the body portion, said body portion and the partition being composed of dissimilar metals, substantially as described.

3. An amalgam-trap comprisingaplate having a recess therein, and a cell in said recess comprising a tubular body portion and a removable partition therein, said body portion and partition being composed of dissimilar metals, substantially as described.

In Witness whereof I have hereunto set my hand.

GEORGE R. TUTTLE.
